Filed Jan. 24, 1936 awam Patented Dec. 21, 1937 PATENT OFFICE" BUTTER-SUBSTITUTE MIXING AND MOLD ING DEVICE Ralph R. Auerswald, San Diego, Calif. Application January 24, 1936, Serial No. 60,587

4 Claims.

My invention relates to a device for mixing and molding butter substitutes such as oleomargarine and the'objects of my invention are: p v

First, toprovide a novel device for mixingbutter substitutes. v

Second, to provide a device for mixing butter substitutes which is very efilcientin its action.

Third, to provide a device of this class which combines a mixing device with a device for .molding the butter substitute. into a small block.

Fourth, to provide a device of this class with a means for latching the molding plunger in certain position while using the device for mixing and which also serves to sever the block at the end when molding.

Fifth, to provide a device of this class in which the several parts are retained in varied relation with each other by a spring latch.

Sixth, to provide a device of this class which is very simple and economical of construction, easy to operate, efficient in its action, and which will 7 not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims reference being had to the accompanying drawing and to the characters of reference thereon which form a part of this application in which:

Figure l is a longitudinal sectional view of my butter substitute mixing and molding device complete showing the moulding cutter in position for cutting the butter substitute block and showing by dotted lines varying positions of the plunger rod and plunger rod head and showing some of the parts in elevation to facilitate the illustration; Fig. 2 is a side elevational view at right angles to that of Fig. 1 and showing the latch and cutter in a position for latching the plunger for mixing purposes by dotted lines; and Fig. 3 is a view from the line 3-3 of Fig. l.

' Similar characters of reference refer to similar parts and. portions throughout the several views of the drawing: 7

The cylinder member I, plunger member 2, plunger rod 3, plunger rod head 4, combined latch and cutter 5, supporting spider 6, and handle I constitute the principal parts and portions of my butter substitute mixing and molding device.

The cylinder member I is a hollow cylinder, preferably square in transverse cross section and provided with rectangular sides. The extended ill-35) end la is chamfered thus reducing the size at this extended end to provide for smooth surface block of butter substitute. In this chamfered end are a plurality of perforations lb in all four sides to facilitate the mixing operation. Secured to the opposite end of this cylinder memberv l is a supporting spider 6 which is preferably provided with four arms So, each of which engages and'is secured toone side of the member I and forms a support therefor. This spider member 6 is provided with a partition 6b in which is'provided an orifice 60. This spider member isalso provided with an annular extending flange 6d which extends from thepartition 6b in the oppo- ..site direction from the arms 6a. In this flange 6d is secured the one end of a handle member 1,

which is provided with a bore 1a conforming to the orifice 60. It is also provided with an enlarged head lb in which is provided a large bore which is adapted to receive the plunger rod head 4, which is a disk member which islprovided with a convex upper side which is preferably slotted. This head 4 is integrally secured to a plunger rod 3 which extends through the bore 1b and la and orifice 6c. The bore 1a and orifice 60 form a guide for the plunger rod 3 while the bore 1c is adapted to receive the head 4 and be latched as will be hereinafter described in the upper dotted line position shown in Fig. 1 of the drawing. Secured to the lower end of the plunger rod 3 is a plunger member 2 which is shaped to conform to the interior of the cylinder l and is adapted to reciprocatetherein. It is provided with upwardly extending corners 2a to form guides in the wall of the cylinder I. This plunger 2 has slight clearance inside the cylinder wall, but at the chamfered end it fits closelv but slidably therein and when in this extended position the head 4 is in the lower dotted line position in the bottom of the bore 70 as shown in Fig. 1 of the drawing. 7

Secured to two of the arms 6a of the spider member 6 are rivet members 511 which extend outwardly therefrom and form pivots at the opposite sides for the combined latch and cutter 5. This latch and cutter 5 is'inwardly extended at point 5b and is adapted to resiliently engage the side walls of the cylinder l, forming a friction shown by dotted line positions in Fig. 2 of the drawing for holding the plunger downwardly to the upper dotted line position in Fig. 1 of the drawing, when the device is used for mixing.

The operation of the device is as follows: The butter substitute is placed in any suitable receptacle. The plunger member 2, rod 3, and head 4 are moved into the cylinder l until the head 4 is positioned in the upper dotted line position of Fig. 1 01' the drawing. The member 5 is then turned on its pivotal axes to the position shown by dotted lines in Fig. 2 of the drawing which holds the head 4 in position. Then the device is used for mixing by pressing thecylinder I with the chamfered end downwardly into the mass in a chopping action. Then when the mass is mixed sufiiciently in this manner the member 5 is shifted to position substantially as shown by solid lines in Fig. 2 of the drawing, the plunger member 2 is forced upwardly while the cylinder is pressed into the mass which fills the cylinder I, after which the device is raised from the mass. Then the device is placed in a substantially horizontal position and the plunger forced into the cylinder 2 by pressure on the head 4, forcing the butter substitute from the chamfered end of the cylinder I when the plunger head is'in the bottom of the bore 1c as shown by dotted lines. The member 5 is then moved over the end and severs the block at the end, providing a smooth end.

Though I have shownand described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended'claims. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a butter substitute mixing and molding device, a hollow cylindrical member provided with a plurality of perforations in one end, a plunger member reciprocally mounted in said cylinder, means for latching said plunger in certain position near the perforated end, and a handle secured to said cylinder, a plunger rod for said plunger extending through said handle, said latch means being in spring engagement with said cylinder and adapted to extend over the end of said cylinder to form a cutter over the end of said cylinder.

2. In a combination butter substitute mixing and molding device, a hollow square in cross section cylindrical molding member provided with a chamfered end provided with mixing perforations in said chamfered end.

3. In a butter substitute mixing and molding device, a hollow square in cross section cylinder member provided with a chamfered end provided with perforations in said chamfered end, a'plunger reciprocally mounted in said. cylinder, and spring latch means for holding said plunger in certain position insaid cylinder, said spring latch means also serving as a cutter over the perforated end of said cylinder.

4:. In a butter substitute mixing and molding device, a hollow square in cross section cylinder member provided with a chamfered end provided with perforations in said chamfered end, a plunger reciprocally mounted in said cylinder, spring latchmeans for holding said plunger in certain .position in said .cylinder, said spring latch means also serving as a cutter over the perforated end of said cylinder, a handle for said cylinder, a plunger rod for said plunger extending through said handle, said handle being provided with an enlarged bore, and a head for said plunger rod. adapted to enter said enlarged bore.
